Infralimbic-basolateral amygdala circuit associated with depression-like not anxiety-like behaviors induced by chronic neuropathic pain and the antidepressant effects of electroacupuncture

Chronic pain, such as neuropathic pain, can lead to anxiety, depression, and other negative emotions, thereby forming comorbidities and increasing the risk of chronic pain over time. Both the infralimbic amygdala (IL) and the basolateral amygdala (BLA) are significantly associated with negative emotions and pain, and they are known to have reciprocal connections. However, the role of IL-BLA circuit pathways in neuropathic pain-induced anxiety and depression remains unexplored. Electroacupuncture (EA) is frequently employed in the treatment of chronic pain and emotional disorders. However, The mechanism by which EA mediates its analgesic and emotion-alleviating effects via the IL-BLA circuit remains uncertain. Here, we used chemogenetic manipulation combined with behavioral tests to detect pain induced anxiety-like and depression-like behaviors. We observed that activation of the IL-BLA circuit by chemogenetic activation induced depression-like behavior of mice. Additionally, we discovered that chemogenetic activation of the IL-BLA circuit successfully prevented the beneficial effects of EA on depression-like behavior brought on by chronic pain in mice with spared nerve injury (SNI). We discovered that SNI-induced depression-like behavior could be mitigated by inhibiting the circuit, and EA had a comparable depressive-relieving effect. Furthermore, the IL-BLA circuit's activation or inhibition had no effect on the anxiety-like feelings brought on by SNI. Overall, our findings identify a specific neural circuit that selectively regulates pain-induced depression-like emotions, without affecting pain-induced anxiety-like emotions. This discovery offers a precise target for future treatments of comorbid pain and depression and provides a plausible explanation for the efficacy of EA in treating depression-like emotions associated with chronic pain.

The Role of Gender in Turkish Women’s Pregnancy Experiences

Background: Apart from the biological changes women experience throughout pregnancy, their exposure to a gender discrimination stemming from cultural values adopted by the society in which they live can make it difficult for them to adapt to pregnancy and thus lead to negative pregnancy experiences. Aim: This research was conducted using a cross-sectional and relation-seeking approach to evaluate the effects of social gender inequality on pregnancy experiences. Methods: Data for this cross-sectional and relation-seeking study were gathered between 25 November 2019 and 25 January 2020 using face-to face interviews the researcher conducted with childbearing women who visited the outpatient clinic and non-stress test units of a hospital for the pregnancy follow-up. Results:: When using the Pregnancy Experiences Scale to assess childbearing women, higher scores indicated more positive emotions than negative emotions. Independent variables that affect the scores on the Pregnancy Experiences Scale include a willingness to be pregnant, the baby's sex, the woman’s income status, gestational week and the Perception of Gender Scale (p<0.005). A positive but weakly significant relationship was found among the total score on the Perception of Gender Scale, the total score on the Pregnancy Experiences Scale and the average scores of positive emotions intensity and frequency in all sub-dimensions (p<0.005). Conclusion: Based on the data, we conclude that women’s pregnancy experiences are generally positive, and that social gender inequality is a significant determinant affecting pregnancy experiences.

The neural mechanisms of the impact of emoji spatial metaphors on emotional perception

Metaphors play a crucial role in language, thinking, and communication. Emoji, as modern metaphors, carry rich meanings and significantly impact emotional expression. While spatial metaphors in emotional lexicons are confirmed, empirical evidence for spatial metaphors in emoji is scarce, and their neural mechanisms are largely unexplored. This study used a spatial Stroop task to investigate emoji spatial metaphors and their effects on emotional perception and neural mechanisms. The results showed that when the positive emoji were in the upper visual field, compared with the middle and lower visual field, the ability to perceive positive emotions was significantly enhanced; Conversely, when the negative emotion emoji was in the lower visual field, the perception of negative emotion was significantly enhanced compared to the middle visual field. EEG data indicate that inconsistencies between Emoji spatial positions and emotional valence lead to increased amplitudes of the Late Positive Component (LPC), revealing heightened neural activity.

Intrusive thoughts and memories in adolescents with major depressive disorder or post-traumatic stress disorder.

Research in adults suggests that intrusive memories and intrusive thoughts (often referred to as intrusive cognitions) are common in members of the general population and are often seen in clinical disorders. However, little is known about the experience of intrusive cognitions in adolescents, particularly in adolescents with major depressive disorder (MDD) and post-traumatic stress disorder (PTSD). The present study sought to gather fundamental data on these phenomena (i.e., frequency, characteristics and appraisals of intrusive cognitions) in adolescents with MDD and PTSD. Adolescents aged 11-18 with MDD (n = 11), PTSD (n = 13) and a non-clinical control group (n = 25) completed structured interviews concerning their intrusive memories and thoughts. Intrusive thoughts were common in all three groups but were particularly frequently experienced in the MDD group. Intrusive memories were expectedly very common in the PTSD group but also experienced by over half of the adolescents with MDD. Both clinical groups reported more negative emotions in response to their intrusive thoughts or memories and appraised these cognitions more negatively than the non-clinical group. Intrusive memories and thoughts are common experiences in adolescents with MDD and PTSD. Emotions and appraisals relating to these cognitions may be targets for psychological intervention in this age group. However, small sample sizes limit the conclusions that can be drawn. Replication is needed with larger numbers of clinical participants.

Economic inequalities in adolescents’ internalising symptoms: longitudinal evidence from eight countries

Research, mainly conducted in Europe and North America, has shown an inequitable burden of internalising mental health problems among adolescents from poorer households. We investigated whether these mental health inequalities differ across a diverse range of countries and multiple measures of economic circumstances. In this longitudinal observational cohort study, we analysed data from studies conducted in eight countries (Australia, Ethiopia, India, Mexico, Peru, South Africa, the UK, and Viet Nam) across five global regions. All studies had self-reported measures of internalising symptoms using a validated scale at two timepoints in adolescence; a measure of household income, household consumption expenditure, or subjective wealth; and data collected between 2000 and 2019. Household income (measured in four countries), consumption expenditure (six countries), and adolescents' subjective assessment of household wealth (five countries) were measured in mid-adolescence (14-17 years). The primary outcome (internalising symptoms, characterised by negative mood, affect, and anxiety) was measured later in adolescence between age 17 and 19 years. Analyses were linear regression models with adjustment. Effect estimates were added to random-effects meta-analyses to aid understanding of cross-country differences. The overall pooled sample of eight studies featured 18 910 adolescents (9568 [50·6%] female and 9342 [49·4%] male). Household income had a small or null association with adolescents' internalising symptoms. Heterogeneity (I2 statistic) was 71·04%, falling to 39·71% after adjusting for baseline symptoms. Household consumption expenditure had a stronger association with internalising symptoms (decreases of 0·075 SD in Peru [95% CI -0·136 to -0·013], 0·034 SD in South Africa [-0·061 to -0·006], and 0·141 SD in Viet Nam [-0·202 to -0·081] as household consumption expenditure doubled). The I2 statistic was 74·24%, remaining similar at 74·83% after adjusting for baseline symptoms. Adolescents' subjective wealth was associated with internalising symptoms in four of the five countries where it was measured. The I2 statistic was 57·09% and remained similar after adjusting for baseline symptoms (53·25%). We found evidence for cross-country differences in economic inequalities in adolescents' internalising symptoms, most prominently for inequalities according to household consumption expenditure. Subjective wealth explained greater variance in symptoms compared with the objective measures. Our study suggests that economic inequalities in adolescents' mental health are prevalent in many but not all countries and vary by the economic measure considered. Variation in the magnitude of inequalities suggests that the wider context within countries plays an important role in the development of these inequalities. Wellcome Trust.

Evaluation of the Multidimensional Personality Questionnaire (MPQ) Unlikely Virtues Scale in the detection of underreporting.

The current investigation was designed to examine the impact of underreporting response bias on the Multidimensional Personality Questionnaire (MPQ) and the utility of the Unlikely Virtues scale in detecting such responding. Study participants were randomly assigned to either the underreporting (n = 100) or standard instruction (n = 224) conditions. All participants first completed a series of extratest measures under standard instruction prior to the MPQ administration. The results showed that individuals in the underreporting condition scored significantly higher on MPQ scales that reflect positive emotionality and self-control and lower on scales that indicate negative emotionality compared to those in the standard instruction. Moreover, the psychometric validity of MPQ scale scores against extratest measures was substantially attenuated in the underreporting condition compared to the standard instruction condition. The Unlikely Virtues scale differentiated between the conditions at a large effect size magnitude (Hedges' g = 1.21) and showed promising classification accuracy though lower cut scores than those reported in the MPQ manual performed substantially better with respect to sensitivity. Future research needs to replicate these findings in more naturalistic settings with other research designs. (PsycInfo Database Record (c) 2024 APA, all rights reserved).

Getting Acceptance for Tough Decisions

This article discusses research-based strategies that organizational leaders can use to effectively implement unpopular decisions and gain acceptance of necessary changes from employees and stakeholders. It outlines the importance of clear communication to explain the rationale and context behind tough choices. Leaders must be transparent in their decision-making process and involve stakeholders to address concerns and build ownership of outcomes. Addressing the negative emotions that arise and exploring alternative options or ways to mitigate impacts can help address psychological and practical issues. Enlisting champions and coalitions of supporters to reinforce the reasoning for decisions can boost consensus. Continued communication on outcomes and progress reinforces that the difficult period was necessary. Ultimately, navigating tough times requires combining these communication strategies with empathetic and honest leadership that cultivates trust and shared commitment to organizational goals and vision despite short-term hardship.

Emotional aftermath of the 2020 U.S. presidential election: a study of hindsight bias in younger and older adults

ABSTRACT Hindsight bias – also known as the knew-it-all-along effect – is a ubiquitous judgment error affecting decision makers. Hindsight bias has been shown to vary across age groups and as a function of contextual factors, such as the decision maker’s emotional state. Despite theoretical reasons why emotions might have a stronger impact on hindsight bias in older than in younger adults, age differences in hindsight bias for emotional events remain relatively underexplored. We examined emotion and hindsight bias in younger and older adults (N = 272) against the backdrop of the 2020 U.S. presidential election. Participants predicted electoral college votes for the two presidential candidates before the election and were asked to remember their predictions approximately three weeks later, after the election results had been finalised. Republicans, for whom the electoral outcome was negatively tinged, exhibited greater hindsight bias for President Biden’s result compared with Democrats, for whom the electoral outcome was positive. The asymmetry in hindsight bias between Republicans and Democrats was similar for younger and older participants. This study suggests that negative emotions may exacerbate hindsight bias, and that adult age differences in hindsight bias observed in laboratory settings may not translate to real-world contexts.

Negative Affect Following Dating Application Use Is Predicted by Social Anxiety Symptoms and Match Rate.

Social rejection is a common and unavoidable experience for users of dating apps. Research suggests that socially anxious individuals may be particularly likely to use dating apps to establish intimate relationships, given their preference for online (vs. face-to-face) communication. However, social anxiety (SA) symptoms are associated with heightened negative affect and decreased prosocial behavior following social rejection, suggesting that exposure to dating app rejection has deleterious consequences in this population. This study examined whether SA symptoms and social rejection (vs. acceptance) feedback interact to predict participants' negative and positive affect and social engagement with dating app matches. Participants (N = 128) evaluated for SA symptoms were randomly assigned to receive high or low match rate feedback on a simulated dating application task. SA symptoms were negatively associated with positive affect following high match rate feedback and positively associated with negative affect following low match rate feedback. SA symptoms were negatively associated with self-reported likelihood of contact initiation with matches. Results suggest that high socially anxious individuals are more susceptible to negative repercussions of social rejection on dating applications.

Using machine learning methods to identify trajectories of change and predict responders and non-responders to short-term dynamic therapy

Objectives Predicting therapy responders can significantly improve clinical outcomes. This study aims to identify predictors of response to short-term dynamic therapy. Methods Data from 95 patients who underwent 16-session therapy were analyzed using machine learning. Weekly progress was monitored with the Outcome Questionnaire (OQ45) and Target Complaints (TC). A machine learning model identified change trajectories for responders and non-responders, with a random forest algorithm and elastic net modeling predicting trajectory group membership using pre-treatment data. Results A weak positive relationship was found between the trajectories of the two outcome variables. The results of the different analysis methods were compared and discussed. Important predictors of OQ45 trajectories, based on random forest modeling, included initial symptom severity, difficulties in emotion regulation, coldness, avoidant attachment, conscientiousness, interpersonal problems, non-acceptance of negative emotion, neuroticism, emotional clarity, impulsivity, and emotion awareness (72.8% accuracy). Initial problem severity, self-scarifying extraversion, and non-assertiveness were the most dominant predictors for TC trajectories (62.8% accuracy). Conclusions These findings offer data-driven insights for selecting short-term dynamic therapy. Predicting response for the OQ45, a nomothetic measure, does not extend to the TC, an idiographic measure, and vice versa, highlighting the importance of multidimensional outcome evaluations for personalized treatment.

A Meta-Analysis of the Effect of Modified Gastric Tube Length on Enteral Nutrition in Stroke Patients

Objective: To systematically evaluate the effect of modified length of gastric tube implantation in stroke patients. Methods: Randomized controlled studies on the effect of narrative therapy on negative emotions of malignant tumor patients were published in PubMed, EMbase, Web of Science, Cochrane Library, CNKY. Wanfang Data, VIP Database and CBM disc from database establishment to May 2021. RewMan 5.2 software was used for the meta-analysis. Results: Ten articles were included, involving 1140 patients in total. Results of meta-analysis showed that improved length of gastric tube implantation could reduce the incidence of aspiration pneumonia in stroke patients with enteral nutrition [OR = 0.18, 95% CI (0.10, 0.31), P < 0.00001], reduce gastroesophageal reflux rate (OR = 0.13, 95% CI (0.04, 0.38), P < 0.0002], the incidence of aspiration (OR = 0.23, 95% CI (0.11, 0.38), P < 0.00001], the incidence of abdominal distension and diarrhea (OR = 0.13, 95% CI (0.06, 0.28), P < 0.00001], the incidence of choking cough (OR = 0.20, 95% CI (0.07, 0.61), P < 0.005], but no difference between the two groups in terms of reducing gastric residual (OR = 0.10, 95% CI (2.40, 2.60), P = 0.94]. Conclusions: The modified length of the gastric tube can replace the traditional length of the gastric tube in the application of stroke patients, can reduce the complications of enteral nutrition, is safe and feasible. However, due to the limitation of the quality and quantity of the included studies, we should be cautious about the results of this meta-analysis and expect to carry out more large-sample and high-quality randomized controlled trials for demonstration.

Insomnia treatment effects on negative emotionality among veterans in treatment for alcohol use disorder.

Insomnia symptoms are pervasive and persistent in alcohol use disorder (AUD), though little is known about the mechanisms that underlie this association. We previously found that cognitive behavioral therapy for insomnia (CBT-I) reduced alcohol-related problems among veterans by improving insomnia severity (NCT03806491). In this planned secondary analysis of the same clinical trial data, we tested negative emotionality as one potential mechanism to explain this effect. Specifically, we tested the change in negative emotionality as a mediator of the association between change in insomnia symptoms and alcohol-related outcomes (craving, heavy drinking frequency, and alcohol-related problems). Participants were 67 veterans in treatment for AUD who also met the criteria for insomnia disorder (91% male, 84% White, average age = 46.3 years). Participants were randomized to five sessions of CBT-I or a single-session sleep hygiene control. Assessments occurred at baseline, immediately posttreatment (~6 weeks after baseline), and at 6-week follow-up. Measures included the Insomnia Severity Index, Penn Alcohol Craving Scale, Timeline Followback, and Short Inventory of Problems. We created a latent negative emotionality indicator based on five validated and reliable measures of negative emotionality. Contrary to hypotheses, CBT-I did not improve negative emotionality relative to sleep hygiene control. However, across both treatment conditions, decreases in insomnia symptoms from baseline to posttreatment were associated with concurrent decreases in negative emotionality, which in turn predicted reductions in alcohol craving and heavy drinking. Negative emotionality may help explain links between insomnia symptoms and alcohol-related outcomes.

The relationship between familial factors and youth mental health outcomes in Korean American families: The mediation effects of youth's negative emotionality.

Depressive symptoms are one of the mental health problems among Korean American (KA) youth. Although several studies examined mental distress among KA youth, few have examined the associations between different familial factors, negative emotionality, and depressive symptoms among them, especially using longitudinal data. Drawing on the Triadic Model of Family Process (TMFP), this study examined the longitudinal associations between Korean-specific aspects of familial factors and depressive symptoms among KA youth and the mediation role of negative emotionality in the relationships. Using KA youth and parent data from the Midwest Longitudinal Study of Asian American Families (MLSAAF) project, path analyses revealed that family enmeshment and youth-reported intergenerational conflict were associated with youth depressive symptoms, with negative emotionality serving as a mediator. The findings suggest that interventions aimed at reducing negative emotionality and improving parent-youth relationship quality and family boundaries could be helpful in reducing youth depressive symptoms.

The Relation between Mentalized Affectivity and Negative Emotions in Chinese College Students: The Moderating Effect of Internet Altruistic Behavior

This article aims to investigate the impact of mentalized affectivity on negative emotions among Chinese college students based on a questionnaire survey of 899 university students. The study adopts a mentalized affectivity scale, an internet altruistic behavior scale, and a self-analysis questionnaire. The study’s findings reveal a negative correlation between mentalized affectivity and depression, anxiety, and stress, but a positive correlation with variables linked to internet altruistic behavior in college students. Additionally, the study reveals a significant moderating effect of internet altruistic behavior on the relationship between mentalized affectivity and depression and anxiety. It is concluded that an increased level of affectivity can help modulate negative emotions and that internet altruistic behavior can play a moderator role in the modulation process.

A common neural response to perceiving but not implicitly regulating infant and adult affect in postpartum mothers

ABSTRACT The transition to parenthood requires parents develop caregiving behaviors, such as the ability to identify their infant’s emotions and regulate their own emotional response. Research has identified patterns of neural activation in parenting contexts that are interpreted as socioemotional processing. However, no prior research has directly tested whether mothers’ neural responses to their infant’s affect are the same as those involved in emotion perception/experience and regulation in other contexts. We employed conjunction analyses to clarify which components of mothers’ neural response to viewing their infant’s affect are shared with passively viewing and labeling adult affective faces (emotion perception/experience and implicit emotion regulation, respectively) in 24 mothers three months postpartum. Our results support a common neural response to viewing infant and adult affect in regions associated with emotion perception/experience (bilateral hippocampi, amygdalae, thalami, orbitofrontal cortex, and ventrolateral prefrontal cortex), but no areas of common response to viewing negative infant affect and implicitly regulating negative adult affect outside of the occipital lobe and cerebellum. This study provides corroborating evidence for shared neural patterns being involved in perceiving/experiencing infant and adult affect but not implicit regulation of infant and adult negative affect.

Self-Choice Emotion Regulation Enhances Stress Reduction: Neural Basis of Self-Choice Emotion Regulation

Background/Objectives: Opting to perform emotion regulation when facing high-arousal stimuli enhances the reduction in negative emotions. Previous research has indicated that self-choice, that is, personally choosing from multiple alternatives, can improve performance. However, it is unclear whether the emotion regulation strategy chosen among multiple alternatives in daily life enhances stress reduction compared to a forced strategy. This study aimed to reveal the effects of self-choice emotion regulation and its underlying neural basis. Methods: Participants were 40 healthy adults who met the inclusion criteria; they performed self-choice emotion regulation, forced emotion regulation, and no emotion regulation (the control condition) while their brain activity was captured using a functional magnetic resonance imaging scanner. First, the participants were shown a stressful scenario. Secondly, they rated the stress they experienced. Thirdly, they performed self-choice or forced emotion regulation or did nothing. Finally, participants rated their stress level again. Results: Self-choice emotion regulation reduced stress better than forced-choice emotion regulation. The stress reduction was associated with decreases in the activation of the left opercular part of the inferior frontal gyrus. Conclusions: Self-choice can improve emotion regulation, and this effect is likely mediated by the neural efficiency of the left inferior frontal gyrus.

The pivotal role of positive emotions in maintaining nurses’ trust and preventing pandemic fatigue

Abstract Background Nursing is a challenging profession that demands quick adaptation to changing conditions. The COVID-19 pandemic has placed unprecedented pressure on nursing teams, leading to high-stress levels and uncertainty. This study examines how nurses’ emotional response at the start of the pandemic predicts their trust in the healthcare system and pandemic fatigue after three morbidity waves. Methods This study included collecting self-reported data among Israeli nurses in three time periods: 346 nurses during March-May 2020 (T1), 260 nurses during June-July 2020 (T2), and 91 nurses during February 2022 (T3). Change in the study variables was assessed using repeated-measure ANOVA. Two multiple linear regression models were calculated for trust and pandemic fatigue at T3, with the emotions at T1 and professional seniority as predictors. Results A significant increase in negative emotions was observed between T1 and T2 (M = 2.65, SD = 1.12 and M = 3.20, SD = 1.29 respectively). Furthermore, there was a significant decrease in trust levels between T1 and T3 (M = 4.68, SD = 1.14 and M = 4.07, SD = 1.08 respectively). The regression model for trust was significant, with 20% of the variance explained in it, revealing that higher positive emotions at T1 predicted higher trust at T3. Similarly, the regression model for pandemic fatigue was significant (R2=22%), showing that lower professional seniority and lower positive emotions at T1 were predictors of higher pandemic fatigue at T3. Conclusions During a crisis, nurses may experience intense negative emotions like fear and anxiety. However, positive emotions, such as pride and a sense of mission, are crucial in maintaining their trust and preventing the onset of pandemic fatigue. Healthcare organizations should promote emotional support and provide emotional resources so that nurses can continue to deliver high-quality care even during challenging times. Key messages • During times of crisis, it’s crucial to foster positivity and encourage a sense of pride and accomplishment in nursing staff. • Healthcare organizations must provide emotional support to nursing teams in routine and crisis situations to prevent burnout and maintain trust and long-term functioning.

Predictive value of Type D personality combined with unhealthy cardiovascular behaviors for the long-term adverse cardiovascular events in ACS patients

Abstract Background Acute coronary syndrome (ACS) has become a major public health problem worldwide due to its high morbidity and mortality. In addition to traditional risk factors, psychosocial factors play an important role in the development of ACS.Type D personality, as a combination of social inhibition and negative affect, has been defined as a psychological risk factor for coronary heart disease by the European Society of Cardiology.Meanwhile, ACS patients with Type D personality may have behaviors such as unhealthy dietary behaviors, less regular physical activity, and poorer self-management behaviors. Then, whether the combination of Type D personality and poor cardiovascular health behaviors can increase the risk of poor prognosis in patients with ACS requires further research. Purpose The aim of this study was to investigate the effect of Type D personality combined with poor cardiovascular health behaviors on long-term major adverse cardiovascular events(MACE) in patients with ACS. Methods A total of 18631 patients diagnosed with ACS between January 2017 and July 2023 were included in this study. Type D personality, cardiovascular health behaviors (smoking cessation, physical activity, average sleep duration at night, dietary assessment index, BMI, lipids, blood glucose, blood pressure) were assessed during the admission period, and were divided into poor, general, and ideal cardiovascular health with a cut-off score of 50 and 80.The binary logistic regression analysis was used to assese the effect of Type D personality combined with cardiovascular health score on the occurrence of MACE (stroke, reinfarction, revascularization, all-cause death). Results The median follow-up in this study was 37 months, and we found that a total of 3750 people had MACE during the follow-up period. The logistic regression result showed that compared with Type D personality (-) and cardiovascular health behaviors (poor) group, Type D personality (+) and cardiovascular health behaviors (poor) group (OR=1.451, 95%CI=1.055-1.995,P=0.022), Type D personality (+) and cardiovascular health behaviors (general) group (OR=1.425, 95%CI=1.092-1.858,P=0.009), Type D personality (-) cardiovascular health behavior (poor) group (OR=1.301, 95%CI=1.013-1.670, P=0.039) were independent risk factors for the occurrence of further adverse cardiovascular events. Conclusion Type D personality combined with unhealthy cardiovascular behavior individuals may be at high risk for MACE. Therefore, early assessment of Type D personality and cardiovascular health behaviors are needed, thereby reducing the incidence of MACE in ACS patients.

Enhancing the Precision of the Self-Compassion Scale Short Form (SCS-SF) with Rasch Methodology

Abstract Objectives Precise measurement of self-compassion is essential for informing well-being–related policies. Traditional assessment methods have led to inconsistencies in the factor structure of self-compassion scales. We used Rasch methodology to enhance measurement precision and assess the psychometric properties of the Self-Compassion Scale Short Form (SCS-SF), including its invariance across Ghana, Germany, India, and New Zealand. Method We employed the Partial Credit Rasch model to analyse responses obtained from 1000 individuals randomly selected (i.e. 250 from each country) from a total convenience sample of 1822 recruited from the general populations of Germany, Ghana, India, and New Zealand. Results The initial identification of local dependency among certain items led to a significant misfitting of the SCS-SF to the Rasch model (χ2 (108) = 260.26, p < 0.001). We addressed this issue by merging locally dependent items, using testlets. The solution with three testlets resulted in optimal fit of the SCS-SF to the Rasch model (χ2 (27) = 23.84, p = 0.64), showing evidence of unidimensionality, strong sample targeting (M = 0.20; SD = 0.72), and good reliability (Person Separation Index = 0.71), including invariance across sociodemographic factors. We then developed ordinal-to-interval conversion tables based on the Rasch model’s person estimates. The SCS-SF showed positive correlations with measures of compassion towards others, optimism, and positive affect, alongside negative associations with psychological distress and negative affect. Conclusions The current study supports the reliability, as well as the structural, convergent, and external validity of the SCS-SF. By employing the ordinal-to-interval conversion tables published here, the precision of the measure is significantly enhanced, offering a robust tool for investigating self-compassion across different cultures.

Avoiding hedonic contrast to increase acceptance of healthy sustainable school meals

Abstract To promote sustainable eating in schools, new approaches for embracing plant-based (PB) meals are needed. Hedonic contrast (HC) describes how liking for one item is influenced by the recent experience of other items of different hedonic valence. Despite its established impact on liking, HC’s effect on intake, particularly in repeated exposure experiments, is limited. Moreover, its effect on food-related emotions remains largely unexplored. Hence, this study investigated how HC influences liking, emotions and intake of an innovative co-created PB dish, served as part of a course meal, at school in a repeated exposure study. Two groups of students (N (HC) =71, mean age=14.5 and N (control) =57, mean age=15.3) were served the same neutrally liked main PB dish (pumpkin stuffed lentils balls (LPA)) after a starter dish (rice with vegetables) which was altered in taste through seasoning and cooking methods to be more (HC) or less (control) tasty. The exposure was repeated once/week for 5 consecutive weeks. Liking and emotional responses for the dishes were recorded through a questionnaire and food consumption by weighting plate waste. HC led to lower liking (p = 0.037) and lower positive emotions (cheerful, pleasure) with high arousal (surprise) for LPA, while increasing negative valence emotions (disappointed). Moreover, LPA consumption was significantly lower in the HC group vs the control (45% vs 60% respectively, p = 0.040), resulting in lower protein intake in the HC group (p = 0.029). The effects of HC remained stable with time. This study, for the first time, reveals a sustained rise in food-related positive high arousal emotions, when foods are presented following less liked food. Since new foods evoking positive valence and high arousal emotions have higher chances to be appreciated than foods evoking positive valence and low arousal emotions, this work opens new perspectives on how to propose new, healthier and more sustainable PB dishes in school canteens. Key messages • Avoiding negative contrast between school meals is a promising strategy to ensure higher liking, intake and increased positive emotions over repeated exposure for innovative plant-based dishes. • To enhance adolescent’s acceptance and uptake of new plant-based dishes in school canteens, it is better to serve them after less tasty options.
